UNITED sra EDWIN II. sPaFroRD, or oAK PARK, ILLINOIS. y

Be it known that I, EDWIN H. SPAFFORD, a citizen of the United States, residing at Oak Park, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Shears-Sharpenels, of which the following is a specification.

My invention relates to sharpening devices and particularly to Sharpeners for shears.

The object of my invention is to provide a shears Sharpener which shall be of simple construction, inexpensive and easily operated.

"1A further object of my invention is to provide a shears Sharpener in which the sharpening element may be readily rearranged to presentfditferentportionsof its surface in position for use, to the end that practicaily all of its sharpening surface may be utilized, and in whiclr the sharpening element may be readily Ih'placed when too badly worn for 'further us thereby prolonging the period of usetulnes the device.

Other obje 'ts will appear hereinafter.

My inventioir` consists generally in a suitable casing, a member mounted in said casing and having an augularly disposed socket or recess and a sharpening element comprising a block of suitable material mounted in said recess, said casing being-,suitably slotted to give access to the sharpening element.

My invention urther consists in a device as mentioned, the several elements of which shall be so proportioned and arranged that the sharpening element may be turned into various positions to present its several faces and portions of its faces into position for ilse.

My invention further consists in various details of construction and arrangements of parts all as will be hereinafter fully described and particularly pointed out in the claims.

My invention will be more readily understood by reference to the accompanying drawings forming a part of this specification and in which,

Figure 1 is a side elevation of the device embodying my invention in its preferred form, Fig. 2 is a ero'ss section on the line :c-- of Iigs. 1 and 3. Fig. 3 is a longitudinal section on the line g/-y of Fig. 2, F 4

is a perspective view of the member for holding the sharpening element and F ig. 5 is a longitudinal sect-ion of a modiiied form of the devlce.

Referring to the drawings, 1 indicates the casing which comprises a rectangular' mem- Speccaton of Letters Patent. I Application fusa December so, 1907. sarai N o. essere;-

ber preferably formed of sheet metal and open at the ends. Mounted in the casing, 1

is a member, 2 which is provided with a suit- I able socket to hold the sharpening element. As shown in Figs. 1 to 4 respectively the member, 2 comprises a block, preferably of wood which fits snuody within the casing, 1.-

The block is inserted in the casing by bein slid longitudinally thereiuto, the ends of the casing being open for this purpose, and is provided with an angularly disposed socket or recess to hold the sharpening element, 3. The element 3 is formed of any suitable material such as carborundum, and is in form a parallelepiped having a square cross section. rl`he block, 2 and the element 3 are of equal thickness and the said element is retained` in the recess by the side walls, 1' of the casing. 4 indicates the recess. This 'is arranged at the same angleto the perpbndicular as it is desired that the bevel .on the blade of the shears shall be, and the element or member, 3 iits snugly therein. Extending from the recess, 4 to the upper edge oll the block is a slot, 5. This is narrower than.` the recess, forming the shouldels 6-6 to liold the member, 3 in place.

The casing, 1 is provided with a slot to re- I eeive the blade, A of the shears, and ermit the same to engage with the mem er,

The slot complises the vertical portion, 7'

having the vertical wall, S, and the offset portion, 9. quite to the upper face of the member 3, the

T he wall, S does not extendfoffset portion thereby forming arecess, 10. r

In sharpening the shears, a wire edge is formed upon the edge of the blade which may be removed after the blade is sharpened by'closmg the blades together several tunes.

It is to prevent interfering with or turningof the wire edge, that the offset portion, 9 or recess, 10 is provided, the side of the blade being held firmly against the vertical wall`,\8 while being sharpened. To

dental dispdaeement of the block, 2 within the member, l the latter is provided with a punch dent, 1l, preferably in its lower wall and the block, 2 with a corresponding coacting dent, 12- i.,

In Fig. 5 I have illustrated. a modiied form of my device wherein a metahstrip, 14, is bent into the form shown to replaethe block, 2. width as the member, 3, and is shapedsiinilarly to the block, 2 for holding said membei- The free endsv of the stri-p are turned upf The strip, 1-1 is of substantially the same y wardly bearing against the portion wliielgtloa'erportionof saidslotbeingofl'setsubstanforms the bottom of the recess, 4, the por tions/"15 of the strip thus forming spriiif'g*- members to retain the device within the casing.

tially as described.

\. 3. In a device of the class described, a cas- 50 v ing. comprising a rectangular member open at lie ends, in combination wth a member` To use the device a bladeof the shears is mounted in said casino' and ha fing an angu- E D 2"* D bearing against the sharpening member, 3,

lacross which it is drawn several times. After lthat each of the four faces may be used.-

mien-the four faces are worn at one end of the member, said member. may be turned. end for end and the four faces at the opposite end utilized, thus eight sharpening surfaces may be used with cach member, 3. 'hen the member is too badly .vorn for further use,

it may vbe replaced by a new one. To turn or re )lace the member it. is but necessary to withdraw thel block 2 from the casing, change the position of the member in the recess and re lace the block.

{aviiig described my invention what I claim as new and desire to secure by Letters Patent is:

1. In a device of the class described, a suitable casing, in combination with a meniber mounted in said casing and having an angular-ly disposed recess therein, a sharpening element mounted in said recess and said casinfr being slotted to permit the blade of the siears to contact said sharpening clement, substantially as described.

2. In a device. of the class described, a casing, in combination with a member mounted' U an angularly dis- 1 iiisaid casing and havin posed recess, therein, a siarpening element arranged in said recess and said casing havingr a slot extending downwardly beyond-the upper surface of said sharpening element, the

i held firmly against tliewall, S with the edge i i t extending angularly therefrom to lariv disposed recess therein, a slot ofv less tdikiie edge of said member and a sharpening T eleiiient mounted in said recess, said casing l having a slot extending belowthe upper surface Rif said element, substantially as described.A G0. .i

A 4. Ina device of the class described, a casing comprising a hollow rectangular member open at the ends, in combination with a member mounted in said casing and having an E viiilili than said recess extending therefronr argularly disposed recess therein, a slot of G5 less width than said recess extending therefrom to the edge of said member and a sliarpeniiig element, mounted in said recess, said casing having "a slot comprising a vert-ical portion extending from the upper edge thereof tn a ioint above the upper surface of the ,sharpening element and an offset Xiortion point beim vsaid surface, substantially as described.

In a device of the class described-a hellen' rectangular casing open at the ends,- in combination with a member fitting snugly xviii-ii said casi-iig and having an singularly disposed recess and a slot of less width than said recess extending therefrom to the upper 8X0 edge of said member and a sharpening ele nient mounted in said recess, said element being square in cross section and of equal thickness with said member, said casing havingr a slot extending from its upper edge to Va point below the upper surface of said elenient, substantially as described.

In testimony whereof I have signed my naine to this specilication in the presence of n tivo subscribing witnesses. EDWIN ll. SPAFFORD.
